> Key: SHINDIG-1669
> URL: https://issues.apache.org/jira/browse/SHINDIG-1669
> Project: Shindig
> Issue Type: Improvement
> Affects Versions: 3.0.0
> Reporter: Ryan Baxter
> Fix For: 3.0.0

> Original Estimate: 48h
> Remaining Estimate: 48h
>
> When you call commoncontainer.navigateUrl if the URL cannot be reached the
> caller has no way of knowing if the URL was navigated successfully or not.
> To solve this we make a head request to the URL we are navigating to and add
> a callback to the API.
> It is important to note that we will not be caching the response of the head
> request. While this could possibly give us better performance we have no way
> of guaranteeing the server will still be up next time and everything may
> fail. This is different from the gadget case where we have the gadget XML
> cached on the server.
